It's been almost a decade since The Bourne Ultimatum; yet Greengrass & co. apparently failed to come up with any new ideas. Jason Bourne is a carbon copy of the previous three titles (The Bourne Legacy doesn't count) only older. Exotic locales? Athens, Berlin, Reykjavik and Rome (among others.) Hazy flashbacks? Check. Implausible one-punch knockouts? Ad nauseam. Sneaky CIA operatives? The more the merrier. If you can explain the difference between Blackbriar, Iron Hand and Treadstone, you're a better man than I am. The action's still first-rate; but as Jones advises, "You have to stop this, and stop it now."
